The funny thing is, a great deal of skylines go through a phase where one tower sticks out while the rest catch up. There feels to be an unwritten law that a building can't go higher than 450 feet and no one dares approach it, even though it's clear, based on other cities our size, we could definitely support a 500 footer - if not more. Maybe it's the conformity effect?
But then one tower breaks through and others follow. Someone mentioned the COB's construction. Prior to its completion, 136 East South Temple was the tallest (not counting the capitol & city hall) building in the city - at only 274 feet. So, even back then, Salt Lake didn't have a 300 footer. COB opens up, and the skyline dramatically went vertical throughout the 70s and 80s. I'm not saying that was the reason, but maybe it did kick start things just a bit?
But prior to that boom, this is what SLC's skyline looked like (photo quality 🞵🞵🞵🞵🞵, but you get the idea):
The COB certainly stuck out.
But like I said, a lot of cities went through that with their skyline. Here's Minneapolis after the IDS Tower was built:
Now THAT is standing out.
I'd like to think it's a skyline going through its awkward teenage phase.
